本研究的目的是評估北臺灣一家油墨製造廠作業人員的勞動工作負荷，同時要設法降低勞工肌肉骨路不適症的風險。運用人因工程因素基準線風險認定(Base-linerisk identification of ergonomic factors， BRIEF)檢核表和關鍵指標法(Key In-dicator Method， KIM) 去評估與鑑定肌肉骨路不適症的風險因子。現場收集的資料包括物料重量、工作姿勢、工作步調、垂直距離、垂直抬舉位移和抬舉頻率。油墨填裝作業人員平均一天要填裝2000個重量各為1公斤的成品罐;油墨包裝作業人員每天總共抬舉4166次，平均抬舉物重為l.44公斤。由BRIEF的分析結果得知:這兩種作業人員都很有可能罹患肌肉骨路不適症。以KIM評估得知油墨填裝與油墨包裝作業人員的風險分數分別為40(中高負荷)與50分(高負荷)。為了減少此工作肌肉骨路不適症的風險，建議把原來的工作桌重新設計並更換。這個硬體改善介入可以讓作業員包裝成品罐時不用彎腰就能很平順且有效率地移動罐子。此外，預估油墨填裝與油墨包裝作業人員的KIM風險分數分別可降到20和30分。我們的建議已經被這家油墨公司採納，並且將會落實在包裝區。

The purpose of this study was to assess the physical workloads for packing tasks in a printing ink manufacturing factory located in northern Taiwan, with an aim to lower the risk of musculoskeletal disorders (MSDs) among the workers. The BRIEF checklist and Key Indicator Method (KIM)
were used to evaluate and identify the MSD risk factors associated with the ink packing tasks. The data collected include material weights, work posture, work pace, vertical distances, vertical lifting displacement, and lifting fre-quency. The ink-filling operator averagely filled 2000 1-kg ink cans per day and the ink-packing operator totally lifted 4166 times per day and the average lifting weight was 1.44 kg/lift. The BRIEF analysis results show that both of the operators have high possibility of developing MSDs. The KIM risk scores were evaluated as 40 (median high load) and 50 (high load) for the ink-filling and ink-packing operators, respectively. To reduce MSD risks for this work, a redesign worktable was suggested to replace the original one. This hardware intervention can allow the operators to move the ink cans more smoothly and efficiently without bending their backs as they pack the cans. Fur-ther, the estimated KIM risk scores were reduced to 20 and 30 for the ink-filling and ink-packing operators, respectively. This suggested change has
been adopted by the ink company and will be implemented in the packing area.
